Float & Thermostatic (F&T) steam traps are among the most reliable and versatile types used in steam systems, especially in applications with varying loads and continuous condensate discharge needs. They operate using two main mechanisms: a float and a thermostatic element. The float, which is attached to a lever-operated valve, rises as condensate fills the trap. This motion opens the valve and allows the condensate to be discharged continuously—ideal for systems with steady or fluctuating load
